TRAIN-PIPE COUPLING.

Specification of Letters Patent.

Patented Aug. 25, 1908.

Application filed July 10, 1906. Serial No. 325,517.

To all whom it may concern:

Be it known that I, ALBERT S. PARSONS, a citizen of the United States of. America, residin at Berkeley, Alameda county, California, ave invented certain new and useful Improvements in Train-Pi e Couplings; and I do hereby declare the fol owing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference mar ed thereon, which form a part of this specification.

My invention relates to coupling for train ipes and has for itsv object a train pipe couping in which are arranged the ends of a large number of pipes capab e of being simultaneously cou led by the couplingof the head, as

well as e ectric conductors and means for coupling them at the same time that the train pipes are coupled, the ends of all pipes and of the conductors terminating in the head.

' Referring to the drawings in which like parts are similarly designated, Figure 1, is a plan view of such a head, and Fig. 2, is a section on the line 22, Fig.1.

The general shape of the coupling head is similar to that now in generaluse for coup ling a sniglle train pipe, but is considerab larger. th

. these points are not concentric but are distributed over the coupl'mg faces in any other desired manner. The coupling head com-- prises a casting 3 with the usual overhang 4,

pipes and electric conduits.- The rubber disk 7 is held in lace by screws 8 and a suitablecement. T ough the several conduits 9 and 10 I pass any fluid as steam, com- 7 pressed air for any desired purposes, as well as illuminating gas. The central opening .on the end of the electric conduit. ranging the ends or ports of the several pipes ,10 as shown so that each will be independe drawings I have shown 9 .independent points to be connected and 10, is larger in diameter at the faceof the coupling than the remainder of the pipes and is preferably but not necessarily used as a steam pipe. Electric wires 11 are connected to the contact plugs 12. Each plug'is surrounded by an insulating sleeve 13 and is yieldingly held by spring 14, said spring and sleeve being seated-on a shoulder 15 flgrmed y arent of the other and having comparatively large rubber surfaces between them, I find that I can dispense with all those devices required to take care .ofleakage and that the joint when made will be perfectlyv tight.

. The contact plugs 12 are rovided with a beveled edge so thatwhen' t e two coupling faces are slid together and locked the oppositely positioned plugs will first contact with one another at their beveled faces, mutually depress one another and be held by their springs in contact when the train pipe coupler heads are in locked position.

I claim, A train pipe coupler comprising a pan of interlocking recessed heads provided w1th a number of independent conduits having their ports terminating in the recess, a yielding packing fixed in the recess having holes registering with the ports of the conduits,

there being a large central port'and a number of smaller ports arranged around the same, insulating sleeves seated on shoulders in some of the conduits, springs mounted in the sleeves, contact plugs supported .by the springs normally held above the face of the acking ring and having beveled ends whereby oppositely positioned plugs will slide on one another.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
